Cable Plugs Matter More than One Thinks

Blog Category: , , by

The wireless access points, cameras and alternative devices being mounted on our ceilings or high up on walls are connecting to our networks – but not all use standard faceplate, jack and patch-cord configurations to do so. Instead, a direct-attachment system is being used, which terminates horizontal cable with a field cable plug that plugs directly into devices.

There are two cable plug options for Category 5e, Category 6 and Category 6A twisted-pair cabling:

  1. Crimp-on plug types
  2. PCB plug types

Crimp-on plug types require preciseness; cabling wires, contacts and plug components must correspond correctly to achieve appropriate electrical performance. A crimp-on plug must be designed for each cable’s geometric differences. A PCB cable plug, for that matter, does not take cabling configuration into account. Installing a PCB cable plug is just like putting on a jack: You terminate the cable onto IDCs and place the plug housing on top. This disassociates the characteristics of the cable and plug when connecting them.

Attaining Wireless via DAS Networks for IoT

Blog Category: , by

While attending an industry conference on Internet of Things (IoT), I came across a comment made by a panelist. A numver of them compared and contrasted the competitive landscape from various perspectives (commercial, industrial, residential and utilities), but one popped up when he spoke about the importance of focusing on infrastructure.

The panelist advised us about the nature of the sometimes-uncertain and/or shifting infrastructure capabilities of platforms, devices and software we rely on. Infrastructure is recommended for communication and a functional IoT. Further, he went on to advise that more awareness should be paid to infrastructure to hinder IoT growth from being impeded because our “things” can not communicate with each other.

Are Category Cables Sufficient for HDBaseT?

Blog Category: , , , by

New discoveries have been made about HDBaseT™ signals over the past couple of years, impacting the types of cables that are best suited to transport these new signals.

Recent test results indicate, category cables – which are optimized for Ethernet traffic – often battle with the HDBaseT signal. The characteristics of category cables are often overkill for HDBaseT applications; other times, category cable characteristics are not sufficient to guarantee a great signal. HDBaseT is a dissimilar type of signal, and 4K video is jolting that threshold even further.

To better understand the capabilities of category cables when it comes to HDBaseT, we want to share the outcome of Belden’s in-house cable testing. But, first, it’s vital  to know what standard we tested to.

Can Silicon Photonics Transform Data Centers?

Blog Category: , , , by

Newish on the data-transmission scene, silicon photonics is an electrifying technology that promises inexpensive, mass-produced optical components through photonics integration – it transfers data among computer chips by optical rays that transports more data in less time than electrical conductors. Since the first commercial product was introduced in 2005, the last decade has seen remarkable progress in technology and development.

A main application area for silicon photonics is cloud data centers, whose footprints continue to grow substantially to accommodate massive amounts of servers and switches. Starting in 2016, many hyperscale cloud content and service providers, such as Facebook and Microsoft, began deploying 100G Ethernet using singlemode optics-based infrastructure in their new data centers to bolster up business growth.

100G Ethernet data center deployment has drawn attention to silicon photonics; many of these singlemode transceiver modules are made with silicon photonics technology.

Ethernet Trends for Data Centre Technology

Blog Category: , , by

40G and 100G Ethernet technology is no longer a distant vision for data centers – it is reality. As data centers of all types continue to expand in terms of traffic and size, 100G is set to become the new standard for high bandwidth and intelligent architecture. It will take some time to develop industry-wide, but 100G is well on its way.

In the initial development of 40G and 100G Ethernet, the IEEE 802.3 Ethernet working group considered only multimode optics and multimode fiber cable solutions (with a reach of up to 150m for 40G and 100m for 100G) for data center applications.

Additional Wireless Access Points: What It Means for Networks

Blog Category: , , by

Ordinarily users will bring up to three devices with them – a smartphone, tablet and laptop, for instance – that will all connect to your network the minute you walks through your doors. (The average U.S. consumer now has 3.64 devices.) These devices are continuously downloading updates, receiving emails and synching to cloud-based storage. According to Dell’Oro, the number of wireless LAN active users is currently outpacing wired LAN users.

This fact alone proves the point that bandwidth capacity requirements are escalating– and we have not touched on the devices that are connecting to enterprise networks as a result of Internet of Things (IoT). VoIP phones, IP surveillance cameras, lighting systems and building controls are all connecting to networks to transfer data, receive data and adjust performance in real time.

Cabinet Load: Why It Matters and Why It’s Changing

Blog Category: , , by

For better use of floor space and decreased operating costs, the goal it have more active gear inside cabinets and enclosures. As a result, they’re getting wider, deeper and taller. In the past, most enclosures offered 42 RUs or 45 RUs of space. Today, many cabinets offer 48 RUs of space – and can offer as many as 52 RUs (or more).

But as cabinets grow in size, they also get heavier. If cabinets get too heavy, the floor may not be able to support the load; the cabinets may also be very difficult to move.

It’s becoming crucial to analyze load ratings (load capacities) when selecting cabinets. Here are the load ratings you need to know:

  • Static load rating: How much weight a cabinet can hold when racks are loaded in the data center
  • Dynamic load rating: How much weight a cabinet can accommodate when shipped fully loaded (important to note with services like Data Center Ready becoming more popular)
  • Rolling load rating: How much weight a cabinet can tolerate as it is moved/rolled across the floor

Why PoE Demands Cat 6A Cable

Blog Category: , , , by

Power over Ethernet (PoE) is ideal for supplying a variety of networking, AV and computing devices without the need for an outlet or adapter. It also reduces the amount of building material required to power and connect a device to a network by allowing a single cable to provide both services.

No longer confined solely to VoIP phones and security cameras, powered devices are increasingly calling for PoE connections; and these devices are requiring higher power levels. Wireless access points, digital signage, videoconferencing systems and laptops all require an increasing amount of power running through their cables. In fact, a new PoE standard, IEEE 802.3bt, supports up to 100 W of power per cable.

However, higher power levels running through a cable can cause performance issues by making the cable hotter; and when the cable gets hotter, insertion loss increases. This increases the chance of a business experiencing productivity-draining downtime and may also damage the cable itself.

The type of cabling selected can make a major difference in terms of how heat inside the cable is managed, as well as how it impacts performance. Category 5e and Category 6 cable can be used to support PoE devices, but Category 6A is preferable for a number of reasons.
